What is Nicotine?

Nicotine is an addictive organic compound found in tobacco plants. Nicotine is a plant alkaloid, which means that it’s a naturally occurring chemical that contains nitrogen. Nicotine‘s stimulating abilities come from the fact that when it binds to receptors, neurotransmitters (messenger chemicals) like dopamine, acetylcholine, beta-endorphin, norepinephrine, serotonin, and ACTH are released in the body.
